Yield performance is an important target in sunflower hybrid breeding. This property, in addition to yield stability, is crucial for producers and it depends on many factors. One of these factors is plant number per area unit. This property is greatly influenced by polyphagous insects, either those residing in the soil (wireworms) or those that attack young leaves (aphids, crickets, etc.). These damages decrease crop stand and yield performance. Because of that, systemic insecticides are often applied in seed treatment. The treated seed is more expensive, but a reduced number of treatments during growing season, better plant stand and improved yield performance compensate for the higher price.
